This is a complete copy of DooM 3. Included is the 3 cd image files, a working cdkey, and a working no cd hack. To install doom3 you will need a cdburning program w/ virtual drive technology, ex:alcohol. You can either burn the images to cds and then proceed to install, or you can mount the first image to a virtual drive and proceed to install. When it asks for second disc, unmount first image and then mount the second image. Same for the third disc. Once installed unrar the nocdhack, and simply copy the hacked doom3.exe over the original doom3.exe(the directory you installed doom3 to).
